I also tried it with this command:

root@ag:~# mdadm --assemble --run /dev/md127 /dev/sdb /dev/sdc /dev/sdd


mdadm: cannot open device /dev/sdb: Device or resource busy


mdadm: /dev/sdb has no superblock - assembly aborted

Hello everyone,
will "beg" to help me!

I do not speak English well and then I rely on google translator. Forgive me for any mistakes !!!

Yesterday I found the sharing of nos. I checked the system, and I saw that the raid was not on! I checked with the gui, and I saw a failed disk. The disk sdc.

I turned off the system, I replaced the disc, I rebooted
I replaced the hard drive but the raid does not start! I do not know what to do.

The version is 0.5.24 Openmediavault

Type RAID: RAID5

Disk:

Disk 1 /dev/sda - System Disk
Disk 2 /dev/sdb - Raid
Disk 3 /dev/sdc - Raid
Disk 4 /dev/sdd - Raid

These answers to some commands:

mdadm -E /dev/sd* | grep event

root@aq:~# mdadm -E /dev/sd* | grep event


mdadm: No md superblock detected on /dev/sda.


mdadm: No md superblock detected on /dev/sda1.


mdadm: No md superblock detected on /dev/sda2.


mdadm: No md superblock detected on /dev/sda5.


mdadm: No md superblock detected on /dev/sdc.

Here, this video should make it easier for you doing the method Tom mentioned:

PS- you do need a live CD to do the method I had in my post.

Thank you all! I solved it!

This is what I see at boot grub, where should I put the word "single"?

Can't you just boot it in single user and change the root passwd?

How to boot into single user?

Thanks.

Quote from "votdev"

Boot another Linux system, mount the OMV filesystem and chroot to it to change the password for root.

Thanks for the replies .
Unfortunately I am not sure I can do everything as you said, you can provide a link from where you follow the step by step procedure? I would be very grateful.

I do not have access to the webgui ... lost that as well!

Help me, I do not remember the password for the terminal, how do I do the reset?
